GHSA-46xp-26xh-hpqh: kubevirt.io/kubevirt (CVE-2025-64324)

Package	Ecosystem	Affected	Fixed in
kubevirt.io/kubevirt	Go	<1.6.1 \|\| >=1.7.0-alpha.0, <1.7.0-rc.0	1.6.1, 1.7.0-rc.0

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

KubeVirt versions before 1.6.1, and from 1.7.0-alpha.0 up to but not including 1.7.0-rc.0, are vulnerable. An attacker who can create a VM that uses the hostDisk feature with the DiskOrCreate option (the hostDisk feature gate must be enabled) can get existing host files owned by more privileged users re-owned to the qemu user, letting the VM read and modify them. Upgrade to KubeVirt 1.6.1 or 1.7.0-rc.0. The source gives no workaround.
